Feature Overview

The Cisco IOS software features supported on the Cisco AS5850 universal gateway in Cisco IOS Release 12.2(2)XA are listed in the following section. These features were previously released on other Cisco platforms. Therefore it is important to note that the Cisco AS5850 platform name may not be specifically noted in the individual feature documents.

Supported IOS Features

The Cisco IOS software features being supported in the Cisco IOS release 12.2(2)XB2 are:

•IP side IVR supports no more than 672 calls (1CT3) at 3-4 calls per second (cps). If the recommended values are exceeded, a high CPU utilization may be observed, resulting in excessive call disconnects.

•The AS5850 supports 4 CT3s worth of traffic per chassis (dual RSCs) with 20ms sampling VAD ON or Off or 10ms VAD ON regardless of codec used. Support for 10ms VAD OFF is required, the session is supported at 1060 per RSC (2120 per chassis) with the addition of one more 324 UPC card per RSC. For the initial release, the use of 10 ms shall be enforced for the system supported per RSC.

RSC Failover Redundancy

•RSC failover redundancy requires a Session Initiation Protocol (SIP) proxy server or gatekeeper. Reallocation of resources occurs with failure of an RSC. The reallocation mechanism is not supported when invoked by fluctuation of either the Ethernet interface or Public Switched Telephone Network (PSTN) trunk interface

Codecs Supported on the Cisco AS5850:

•g711u-law

•g711a-law

•g729r8

Determining Platform Support Through Cisco Feature Navigator

Cisco IOS software is packaged in feature sets that support specific platforms. To get updated information regarding platform support for this feature, access Cisco Feature Navigator. Cisco Feature Navigator dynamically updates the list of supported platforms as new platform support is added for the feature.

Cisco Feature Navigator is a web-based tool that enables you to determine which Cisco IOS software images support a specific set of features and which features are supported in a specific Cisco IOS image. You can search by feature or release. Under the release section, you can compare releases side by side to display both the features unique to each software release and the features in common.

To access Cisco Feature Navigator, you must have an account on Cisco.com. If you have forgotten or lost your account information, send a blank e-mail to cco-locksmith@cisco.com. An automatic check will verify that your e-mail address is registered with Cisco.com. If the check is successful, account details with a new random password will be e-mailed to you. Qualified users can establish an account on Cisco.com by following the directions at http://www.cisco.com/register.

Cisco Feature Navigator is updated regularly when major Cisco IOS software releases and technology releases occur. For the most current information, go to the Cisco Feature Navigator home page at the following URL:

Platform support for particular Cisco IOS software releases is dependent on the availability of the software images for those platforms. Software images for some platforms may be deferred, delayed, or changed without prior notice. For updated information about platform support and availability of software images for each Cisco IOS software release, refer to the online release notes or, if supported, Cisco Feature Navigator.

Configuration Tasks

The Cisco IOS voice features supported on the Cisco AS5850 are already supported on other Cisco access server models, including the Cisco AS5300 series and the Cisco AS5800 universal access server. Configuration tasks for Cisco IOS voice features are described in many different documents.

This guide provides an alphabetical reference to voice commands used to configure voice software features. See the "Supported IOS Features" section below for information regarding specific chapters to reference.

Configuration Examples

Configuration examples are found the individual Cisco IOC documents referenced in the "Supported IOS Features" section on page 4.

Command Reference

There are no new or modified commands on the Cisco AS5850. All Cisco IOS commands used are documented in the Cisco IOS Release 12.2 command reference publications, and in the individual Cisco IOS documents listed in the "Supported IOS Features" section.
